Hello:
Does this MpServicesTest app have been merged into master branch?
I could not find it in current GitHub code base.
Thanks

主题: [edk2-devel] [PATCH v2 2/2] MdeModulePkg: Add new Application/MpServicesTest application
The MpServicesTest application exercises the EFI_MP_SERVICES_PROTOCOL.
usage:
MpServicesTest -A [-O]
MpServicesTest -T <Timeout>
MpServicesTest -S <Processor #>
MpServicesTest -P
MpServicesTest -U <Processor #>
MpServicesTest -W
MpServicesTest -E <Processor #>
MpServicesTest -D <Processor #>
MpServicesTest -h
Parameter:
-A: Run all APs.
-O: Run APs sequentially (use with -A).
-T: Specify timeout in milliseconds. Default is to wait forever.
-S: Specify the single AP to run.
-P: Print processor information.
-U: Set the specified AP to the Unhealthy status (use with -E/-D).
-W: Run WhoAmI and print index of BSP.
-E: Enable the specified AP.
-D: Disable the specified AP.
-h: Print this help page.
